ADJUSTABLE HOLDER FOR BRUSHES OR BROOMS.

SPECIFICATION forming part of Letters Patent No. 714,089, dated November18, 1902.

Application filed .Tnly 3,1902. Serial No. 114,258. (No model.)

To all whom, t may concern:

Be it known that I, ALEXIUS WURM, a citizen of the United States, and aresident of West Hoboken, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in AdjustableHolders for Brushes or Brooms, of which the following is aspecification.

This invention relates to adj ustable holders for brushes and brooms,the main object being to provide a holder by means of which a brush-heador broom-head may be quickly adjusted and securely held in any one ofseveral positions for the purpose of brushing or cleaning the cornersof' a room thoroughly at the intersection of the side walls with theceiling and also at other points.

In carrying my invention into effect I make use of a holder having twomain parts, one of which is adjustable on and is preferably oscillatoryrelatively to the other, and means for retaining these two parts in anydesired adjusted position to hold the-brush-head or broom-head which issecured to one of the members at the desired angle with respect toahandle to which the other member of the device is fastened. One ofthese two main members will preferably have a plurality ofholding-faces, which may be at faces intersecting one another, and anyone of these faces may be engaged and held by a strong spring, such asan arched plate-spring, which will engage a considerable portion of such'dat surface. These iiat faces may be formed on the periphery of apivoted block fastened to the handle of the brush or broom and in suchcase will usually be perpendicular to radii passing through the centerof oscillation of such member. In order to assure the permanent locationin the desired angular position with respect to the handle, an auxiliarydevice, such as a clamp-screw, may be employed to lock the two membersof the holder together positively.

In the drawings accompanying this specification and forming part of thepresent application, Figure l is an end elevation, partly in section, onthe line 1 l, Fig. 2, of an adjustable holder constructed in accordancewith my invention and shows the normal positions of the parts in fulllines, the other positions being indicated by dotted lines. Fig.

2 is a side elevation of the same with parts of the brush removed.

As before stated, my improved adjustable holder has two main partsmovable relatively to each other to change the relative positions of thebrush or broom and its handle. One of these parts is a base-piece in theform of a xed block or housing, such as 2, and is preferably secured tothe back of an ordinary brush 4 by means of screws 5. The other memberin the construction shown is a pivoted block, such as 3, which may bemounted on a pin 6 for oscillation between the side walls 16 of thefixed block or base 2. The pivot of the swinging block 3 may be a pin orrivet, a machine-screw having a smooth shank, or any similar element.

The swinging block 3 has a plurality of holding-faces, vany one of whichmay be brought into line with the handle of the brush and snapped intolocking engagement with asuitable spring. Theseholding-faces arepreferably fiat portions of the periphery of the block 3 and may be soplaced as to permit the brush-head to be turned in one direction onlyfrom a central position or in both directhe faces 8 and 9, respectively.All of these faces are preferably perpendicular to radii, passingthrough the axis of oscillation of the swinging block 3.

All of the holding-faces just described are located substantially at oneside ofr the axis of the swinging member 3. At the other side thereofsaid member preferably has a screwthreaded shank 13, which may bescrewed into a correspondingly-threaded bore in a socket adapted. toreceive the end of the brushhandle. The sides of the swinging block 3are preferably hollowed out or cupped, as shown at12, to reduce theweight of the block.

Between the side walls 16 and 17 thereof IOO the base 2 of the holder isso shaped as to proing-faces of the swinging block. This spring shouldbe a strong arched plate-spring, substantially as shown at 14:, whichwill always be in contact with one of the faces of the swinging blockand will preferably engage a considerable portion of the length of suchface. It will be evident that as the spring engages each face at thecenter thereof, which is the point nearest the axis of oscillation ofthe block, the spring tends to center itself on each face with which itcoperates, and considerable force must be exerted to cause thebrush-head to turn and the spring to ride up the cam-slope of any ofsaid faces. Any one of the live faces of the swinging block may bebrought into engagement with the central portion of the arched spring14, as shown in Fig. 1, and the brush-head correspondingly located andlocked in any one of four positions, two at each side of the normalcentral position shown in full lines, the position to which thebrush-head is shifted being of course dependent upon the position of theWall or other surface to be brushed relative to the handle 21.

vIn order to keep the spring 14 from falling out, the block 2 may haveend Walls, such as 15, rising from the spring-supporting face 14'; butthese end walls should not be close enough together to prevent theproper operation of the spring.

In connection with the spring 14 and the fiat faces cooperativetherewith for locating and holding the swinging block I may make use ofan auxiliary locking device, such as the winged clamp screw 17, whichpasses through an opening in one of the Walls 16 of the fixed block 2and impinges against the adjacent side of the swinging block 3. When theparts are in the desired adjusted position, this screw may be turnedslightly to clamp the main members positively together, and a slightturn in the opposite direction is sufficient to release the clamp-screw.In this construction the socket for the end of the handle 21 is a sleeveor ferrule 19, pinned to said A holder constructed in accordance with myinvention constitutes a very sim ple and practical device for adjustinga brush-head to and locating and locking it in any one of a plurality ofpositions and facilitates greatly the work of cleaning Walls, ceilings,and corners, especially when these are formed at varying angles withrespect to one another, and the thorough cleaning of such walls, dac.,is assured when an adjustable brush-head of this type is used.

What I claimis- 1. An adjustable holder for brushes and brooms,comprising a pair of relatively movable members secured respectively tothe handle and to the head of the article one of which members has aspring and the other of which has a plurality of holding-facescoperative respectively with said spring for locating said members indifferent relative positions and lockin g them together.

2. An adjustable holder for brushes and brooms, comprising a pair ofrelatively movable members secured respectively to the handle and to thehead of the article one of which members has a spring and the other ofwhich is oscillatory on the first and has a plurality of fiatholding-faces substantially perpendicular to radii drawn through thecenter of oscillation and cooperative respectively with said spring forlocating said members in different relative positions and locking themtogether.

3. An adjustable holder for brushes and brooms, comprising a base and ablock one secured to the handle and the other to the head of thearticle, said block being pivoted on said base and having a centralholding-face and holding-faces at one side of said central face, and anarched plate-spring supported on said base and cooperative with saidholding-faces respectively for locating said block in different relativepositions and locking it to said base.
